Abstract
A work transfer device executes a generally rectilinear path of movement for progressively transferring articles between successive stations. Transverse vertical motion is imparted via a guide rod which is bodily transversely displaced while maintained parallel with the longitudinal travel of the carriage members. Slides are shiftable longitudinally on the guide rod. Vertical rods project from the slides through the carriage members to support a walking beam type transfer bar. The guide rod is displaced by a double bellcrank mechanism thereby imparting vertical transverse motion to the walking beam.
Claims14
In a work transfer defice for progressively transferring articles to successive stations having a base on which a carriage means is longitudinally shiftable, work engaging means movable longitudinally with the carriage means while being shiftably mounted on the carriage means for transverse shiftable movement with respect to the carriage means, drive means for shifting the carriage means longitudinally of the base and for shifting the work engaging means transversely of the carriage so as to cause the work engaging means to execute a generally rectilinear path of movement for progressively transferring articles between successive stations, the improvement for imparting transverse motion to the work engaging means wherein there is provided a cylindrical guide rod parallel to the direction of carriage travel, a pair of longitudinally spaced slides which are longitudinally shiftable on the guide rod, means securing each slide to the work engaging means, a pair of bellcranks spaced longitudinally apart, means mounting the bellcranks on the base about respective longitudinally spaced pivot axes, a pair of pivot blocks secured to the guide rod at longitudinally spaced locations, each bellcrank having a crank arm connected at the distal end to a corresponding one of the pivot blocks whereby a pivot connection is provided between each crank arm and the corresponding pivot block, each bellcrank comprising a second crank arm, a drag link connecting both second crank arms together so that rocking motion of one crank arm about its pivot axis is imparted to the other crank arm and means operably coupling the two crank arms to the drive means for causing the crank arms to operate in unison to transversely displace the guide rod and thereby impart transverse motion to the work engaging means.
